Characteristics of a universal simulator

Study narrows the scope of research on quantum computing

According to many scientists, quantum computers will have great importance in the future but, despite all efforts, research in this field is still in its infancy. One of the difficulties is understanding what criteria a quantum system should meet to be able to solve problems that are impossible for conventional computers. An international research team headed by SISSA has just published a study that establishes a basic characteristic that universal quantum simulators should possess.
